Abstract
In one implementation, the disclosure provides a system including a first circuit to compute a timing error based on a received error signal and an estimated interference signal and a timing loop filter to output a frequency offset and a phase shift based on the timing error received as input. The system also includes a phase accumulator to accumulate at least a phase shift to generate a sample index and phase and an interpolation filter to generate samples of a side track signal using the sample index and phase.
